Sammi was wriggling on her window perch enjoying the sun so I decided to go get the camera and take a video. Within a few seconds she wriggled off her perch. If she still had her missing front leg she may have been able to catch herself. But she wasn't hurt. She slid down about 2 feet and was up & running before I could get to her. I'm not sure which one of us was more shocked and upset. I suspect the "mom" took it harder than Sammi did.
